Link to A+ Math at bottom of page for additional practice on your strategies Partial SumsWhen using partial sums you can work and solve the problem from left to right. You will be working with each place value when solving for the problems. Let's work with the problem:
515 + 242 = ???
To start we are going to add the numbers in the 100's place value: 500 + 200 = 700
Now, add the 10's place value: 10 + 40 = 50
Next, add the numbers in the 1's place value: 5 + 2 = 7
The last step is to add all the numbers together to get your sum: 700+ 50 + 7 = 757
